You can't run RSG (Router Screenshot Grabber) because it is for web based routers.
So after you got into the this router with telnet, can we see the screen?
However, please don't show the following info:
#1 You full MAC address(es). If you wish to show any MAC address(es), please show only the first three pair(s). Example my first three pairs of my MAC address is 00:10:B5 (also written as 00-10-B5). This info only tells users what is the brand of my NIC (Network Interface Card) is, also maybe the model.
If you show your full MAC address, it tells people the brand, model, and serial number. Not good, unless you like that info public.
#2 Your pppoe / PPPoA user name. It could be in the format of username or username@ISP. If you wish to show your pppoe/PPPoA user name, please only show the @ISP part.
#3 Any serial numbers.
#4 Your SSID, WEP / WPA key, if you are using a wireless router.
#5 Your full "real" public IP address, which will be an IP address outside of those three ranges:
b) 172.16.*.* to 172.31.*.*
If you wish to show your "real" public IP, please only show the first two octets. For example if your IP address was 18.104.22.168, the first two octets would be 70.110.
What someone should really needs to do is a make a tool that maps out networks, and tells the user where that device is located. As to why, simple: To help users, so they know which routers that they own and don't own. ;)
If you legally own both of those routers, you are golden. Well not literally, but you get the idea.
